| titleOfInvention | METHOD TO PRODUCE Ag-Au CHALCOGENIDE |
| abstract | FIELD: electricity. n SUBSTANCE: invention relates to technology of high-temperature synthesis of gold and silver chalcogenides, namely, Ag 3 AuX 2 , where X=S, Se - utenbodaardtite (α-Ag 3 AuS 2 ) and fishesserite (α-Ag 3 AuSe 2 ). Au-Ag chalcogenides are produced from high-temperature melts of stoichiometric composition of a mixture of elementary components taken at ratios corresponding to the synthesized composition with excess of chalcogen in the amount of at least 0.04 wt % from the total charge. The mixture of elementary components is placed into a quartz lamp equipped with a rod to minimise its free volume, the ampoule is sealed and vacuumised, the mixture is heated higher than temperature of synthesized compound melting with the speed of 0.2-0.5°C per minute, sustained at this temperature to produce a homogeneous melt, the melt is cooled down to the temperature below the melting temperature of the produced compound with the speed of 0.2°C per minute, the produced compound is annealed at this temperature, then ampoule is cooled down to ambient temperature. n EFFECT: invention makes it possible to produce a microcrystalline sulphide or selenide of gold and silver of a homogeneous composition, and also provides for explosion-proof conditions of their production. n 2 dwg, 1 ex |
